About Immunodeficiency Symptoms
One of the most common signs of immunodeficiency is an increased susceptibility to infections. You may have infections that are more frequent, longer lasting or harder to treat than are the infections of someone with a normal immune system. You may also get infections that a person with a healthy immune system likely would not get (opportunistic infections). Signs and symptoms differ depending on the type of immunodeficiency disorder, and they vary from person to person.
